[ALSA] soc - ASoC 0.13 AT91xxxx I2S

This patch updates the AT91xxxx I2S driver to the new API in ASoC 0.13.
Changes:-
o Removed DAI capabilities matching code in favour of manual matching in
the machine drivers.
o Added DAI operations for codec and CPU interfaces.
o Removed config_sysclk() function and struct snd_soc_clock_info. No
longer needed as clocking is now configured manually in the machine
drivers. Also removed other clocking data from structures.
